The next step is to create the Rear Wheel Assembly. You will need the components shown below to complete this step.

To begin, use four M2.5x20+6 standoffs and four M2.5x6 screws. Attach the standoffs to the chassis plate as shown.

Grab the yellow motors and chassis. Use four M3x25 screws, four spring washers, and four M3 nuts to assemble the two motors as shown below. When installing the motors onto the chassis, make sure that the read and black wires are facing inside. Place the wires through the hole as shown below.
